Abstract: A lifting arm arrangement for lifting a pipe includes a pipe stacking tool comprising a first end, a second end, and a pipe handling head arranged at the second end. The pipe handling head is configured to grip around the pipe. A gripper head is connected to the first end of the pipe stacking tool. A tilt shaft is configured to connect the pipe stacking tool and the gripper head so as to form an articulated joint. The articulated joint comprises a locked position in which the pipe stacking tool is prevented from tilting about the tilt shaft, and a neutral position in which the pipe stacking tool is allowed to tilt about the tilt shaft.

Abstract: A method for detecting an influx in a wellbore with first and second pressure transmitters arranged in a fixed vertical distance in relation to each other. The method includes calculating an expected density of a return flow between the first and second pressure transmitters, continuously measuring an actual density of the return flow based on a measured pressure at the first and second pressure transmitters, comparing the calculated expected density of the return flow and the measured actual density of the return flow to determine the influx in the wellbore, and predicting a probability of hydrates forming in the well by measuring a temperature via a temperature transmitter arranged in a section of the well adjacent to the first and/or the second pressure transmitter, and using the temperature together with the measurements from the first and second pressure transmitters.

Abstract: A reflector reflects electromagnetic waves, which waves are emitted into a conducting structure from at least one antenna situated at a distance (d′) from the reflector. The distance (d′) is calculated based on measured emitted and reflected waves to and from the reflector, respectively. The reflector includes a reflector disc, an elongated body having a first longitudinal end and a second longitudinal end, the first longitudinal end being fastened to the reflector disc and the second longitudinal end being fastenable to an accumulator piston. Said elongated body further comprises at least two telescopically interconnected reflector tubes rendering reversible adjustment of the elongated body's longitudinal length around a predetermined equilibrium length possible. A piston accumulator applying the reflector, and a method for measuring the distance (d′) are also provided.

Abstract: A drilling system includes machines, process sensors, and a drilling ECU. Each machine has machine sensor which senses an operating state and an operating range with a lower and upper limit. Each process sensor has a process sensor value and a process range with a lower and upper limit. The drilling ECU includes a data processing apparatus and a memory. The memory includes a process model with expected values of the process sensors as a function of a drilling depth, and a reservoir model with geological data. The drilling ECU receives the process sensor value and the operating state, calculates first differences between the process sensor values and the upper limit and/or the lower limit of the process range, calculates second differences between the operating state and the upper limit and/or lower limit of the operating range, and displays the first and second differences on a drilling screen.
